Why is the speed limit of high-speed tunnel 80? Why would someone change lanes and overtake? Aren't you afraid of deducting points and fines?

From Jiangxi to Hubei, it passes through the Hubei-Jiangxi tunnel group at the junction of the two provinces. I remember that the longest tunnel is about 6.9 kilometers with a speed limit of 80 kilometers per hour. It will take 5 to 6 minutes to run this tunnel. Turn on the lights when you go through the tunnel, and you can't keep changing lanes to overtake. But I found that some people not only change lanes, but even speed.

First, why is the speed limit of expressway tunnel 80 km/h?

There are three kinds of maximum speed limits of expressways in China, which are 100 km/h, 1 10 km/h and 120 km/h, respectively, and they are classified according to grades. However, on any expressway, the speed of the tunnel is limited to 80 km/h, which is mainly due to two reasons:

First of all, the view of the tunnel is not good.

Almost all tunnels are dug in the mountain and pass through the center of the mountain. Generally speaking, there are lights in tunnels. However, the view in the tunnel is also very poor. On the one hand, the light is darker than outside, so you have to turn on the light. On the other hand, if you look ahead, you can only see the road conditions hundreds or tens of meters ahead, which makes you feel like driving at night.

The tunnel is completely closed, and in the mountains, the air is generally humid. Once an accident happens in the tunnel, if there is no speed limit, the car behind is likely to avoid it. The speed limit is also to find unexpected situations in advance. Moreover, there are bends in the tunnel, and the view is even worse.

Second, the light coming in and out of the tunnel will make your eyes uncomfortable instantly.

Anyone who has driven in the tunnel knows that at the moment of entering and leaving the tunnel, due to the strong change of light, the eyes will feel uncomfortable for a moment. For example, when it is sunny outside, it will turn into night as soon as he enters the tunnel. If this time is not limited, it is easy to have an accident.

It's the same problem when you leave the tunnel. Your eyes need time to adapt to this change. Many accidents in the tunnel happen where you go in and out of the tunnel. Many cars don't slow down and then enter the tunnel, and their eyes don't adapt for a while, but the front car slows down and the rear car is fast, which will naturally lead to a rear-end collision. So speed limit is a way to solve this kind of accident.

Third, there is no emergency lane in the tunnel, and the deceleration is to prevent accidents and inconvenient rescue.

There are emergency lanes in non-tunnel sections of expressways, except in tunnels. If the tunnel speed limit is lower, once a traffic accident occurs, the rescue will be more troublesome. In order to reduce such incidents, the speed limit in the tunnel is low.

Generally, before entering the tunnel on the expressway, there will be signs telling the length of the tunnel and the required speed limit of 80 km/h, and there will be cameras near the speed limit signs to capture the speeding behavior. Then why did someone change lanes at the speed limit in the tunnel?

There are three main reasons:

1, there is no camera to change lanes and overtake, and there is a camera to drive honestly.

When mobile navigation is opened, you can see at a glance where there are surveillance cameras on the highway. When driving, many drivers rely on mobile navigation to identify and avoid these cameras, put on a show before entering the tunnel, slow down to 80 km/h, and choose a place without cameras to change lanes and overtake when driving in the tunnel.

As long as the camera doesn't catch it, these people can't be punished for their traffic violations. Punishment depends on evidence. Unless someone photographs these violations and gives them to the traffic police, these people will still drive like this. This is simply opportunistic, and something will happen one day.

Some novice drivers really don't know the speed limit in the tunnel.

I have a colleague who has got a driver's license for more than two years and has been on the expressway several times. Once he received a notice of violation, saying that he was speeding in the tunnel. I asked him how fast he was driving. He said that the speed limit on the expressway was not 120km/h, and he said that he was driving around100km/h. I said that you didn't know that the speed limit in the tunnel was 80 km/h, but he said that he didn't pay attention. I really don't know.

This kind of illegal behavior was only known after receiving the information, so they won't dare to violate the rules next time.

3. Many old tunnels don't have cameras.

Some highway tunnels built in the early days did not have cameras. I once drove on a business trip with a colleague. He is a driver. When crossing a tunnel, he thought that the big truck in front was driving slowly, so he was speeding, changing lanes and overtaking in the tunnel, which made me look stupid. I said you just violated three rules, speeding in the tunnel, reaching 90 per hour, and overtaking illegally by changing lanes with a solid line. As a result, people.

Someone else has the steering wheel. what can I do? Although this behavior has not been filmed, the danger is still very early. The fundamental reason why overtaking is not allowed in the tunnel is for safety. Some accidents on the expressway are caused by overtaking in changing lanes. It is difficult to have an accident when driving in your own lane without changing lanes. In addition, the light in the tunnel is poor, the line of sight is poor, and there is no emergency lane. If you don't grasp it well, it is easy to have big problems and it is not convenient for rescue.

4. There is a vehicle failure or accident in the tunnel, and this lane is impassable.

Once when I came home, I met a car that broke down in a highway tunnel. The car broke down on the road and there was no emergency lane in the tunnel. The car in front broke down and the whole road was blocked. The driver called the police and the traffic police haven't arrived yet. There is no way to stop. This is a special case, I believe the traffic police will understand.

Finally, let's talk about the punishment of tunnel violation. 200 yuan will be fined 3 points for overtaking when changing lanes at high speed.

The penalty for speeding in high-speed tunnels is the same as that in non-tunnel sections. If the overspeed is within 10%, give a warning or deduct 3 points; If the overspeed/kloc is within 0/0 ~ 20%, 3 points will be deducted for 50 yuan; If the overspeed is less than 20~50%, 200 yuan will be deducted 3 points; If the speed limit is within 50~70%, 6 points will be deducted and a fine will be imposed 1000 yuan; Depending on the seriousness of the case, the driver's license can be revoked, and the driver's license can be revoked. For speeding 100%, 12 points will be deducted directly, and the driver's license will be revoked and a fine of 2000 yuan will be imposed.
